LED strip attachment

Those of you who have installed some LED strips on the interior of your vehicles, how have you attached the strips to the plastic? I got a 5 meeter strip that I have ready to attach to certain parts of the interior, but the 3M tacky strip that I have on the back of the light strip is not going to stay on the plastic. Any ideas on how to attach so it will stay? Maybe some hot glue?

I did try to attach the strip to the plastic. I had just a 6 inch strip and it didn't want to stick at all. It is very possible that I had some sort of Armorall or something on the dash, but either way, it didn't want anything to do with staying on there.
